or DES MOINES} FLOOR CONSTRUCTION.

Original application filed October 30, 1925, Serial No. 65,883. Dividedand this application filed De:

cember 27,1926. Serial No. 157,342.

The invention relates to floor construction embodying among othercharacteristics pan moulds having supporting means upon the meetingedges thereof to provide a rigid sup- 5 port andaleak-proof joint forthe moulded pans in position.

' This case is a division of my patented invent-ion, filed October 30,1925, Serial No. 65,863, patented December 28, 1926, and bearing thePatent Number 1,612,704, and which embodies a species of inventionpreviously divided from the above entitled patent.

l/Vith the above and other objects in view, the invention furtherincludes the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the appended claims.

In the drawings: Figure 1 is a transverse section of the pan moulds inuse. I

Figure 2 is a perspective of the pans.

Figure 3 is a similar view of a tapered end an. t c p Referring to thedrawings in detail, wherein like characters of reference denotecorresponding parts, the reference character 10 indicates apanpreferably substantially U- shaped in cross section and whichprovides outwardly and obliquely disposed side walls 11.

The lower edges of said side walls 11 are bent outwardly to providesupporting flanges v 12, transversely disposed with respect there-. toand in spaced parallel relation to the top of the pan. The flanges 12when disposed in juxtaposition to companion flanges carried upon themeeting side edges thereof provides a socket within which supportingbeams 13 Figure 1 of the drawings.

Elongated and angularly disposed plates lat are carried upon theundersides of the flanges 12 and extend axially of the longitudinalcenters thereof. The offset portions of said angle plates are inwardlydisposed while the upright portions thereof abut the opposed side edgesof the supporting beams 13, said beams being thus held againstdisplacement. The disposition of the angle plates 14 upon arepositioned, substantially as illustrated in the flanges 12 and theoffsetportioniof said angle platesdisposed in direct alinementwith thesides-l1 of the panslO define channel portions 15 Within which theopposed ends of spreading means, such as illustrated in Figure 10f thedrawing, are receivedto prevent said plates from buckling and to retainthe same upon the supporting beams 13. The 1 spreading meansalso'carries supporting members for engagement with the undersides ofthe top of said pan to prevent thesame from bending under the weight ofthe material poured thereon.

The moulded material is preferably concrete and in the instance of.

constructing floors it is desired to enlarge and strengthen the joistsmoulded between the ad acent side walls 11 of companion pans,

I provide what is termed a tapered end pan 16. The said tapered endpansare of identical construction as that of the pan 10 save for'thetapering of the side walls 17 thereof. Flange members and angle platesof j identical construction and relative association to those asembodied in the plate or intermediate pan 10 are embodied in the tapered.end pans 16.

-Whe n moulding the enlarged ends or en tremities of the joistsabuttinga "wall, ends 18 are employed for abutting off the reduced end of thetapered end pans 16 to prevent undue loss of the material moulded. Thesaid e-ndsare disposed wholly within the enclosure defined by the panproper, thereby leaving the channel port-ions free for the reception-ofthe spreading means therein.

As mentioned in'the foregoing, the spread ing means consists of achanneled bar 19 adapted to position its respective ends within thechannel portions 15 created and formed by the relative association ofthe flanges 12 and angle plates 14, said channel bar providing elongatedslottedportions 20 preferably located at an intermediate point in itslength and which is adapted to receive therein the I aforementioneduprights indicated at .21. The said upright provides rack teeth 22 upon"one side edge thereof for engagement with the f edges of said elongatedslotted portion 20.

These teeth areheld in engagement with the. particular portion ofthechanneled spreader bars 19 through the instrumentality of a wedge member23 dropped behind one side edge of the upright 20 in diametricallyopposed relation to that of the rack teeth 22.

From the foregoing description and accompanying drawings, it will benoted that the V invention provides an exceedingly useful andadvantageous form of moulding apparatus which will effectually and morequickly mould the floors of the modern concrete construction building.

The inventlon 1s susceptible of various changes in its form, proportlonsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having thus described the invention, I-

claim; 7 v

1. A floor construction comprising pan moulds having downwardly andobliquely disposed side walls terminating in outwardly and transverselydisposed flanges, and angle plates carried by the flanges.

2.; A floor construction comprising pan moulds having downwardly andobliquely disposed sides terlninating'in outwardly and transverselydisposed flanges, and angle plates disposed longitudinally of and uponduced ends of the tapered end portion to terminate a mould of a desiredlength.

In testimony whereof I afi'ix my signature.
